ACE: A Cardinality Estimator for Set-Valued Queries

Summary: ACE: an attention-based cardinality estimator for set-valued queries that compresses datasets via a distillation encoder into a compact matrix and uses attention to capture correlations among query elements. Pooling+MLP handles variable-sized queries, avoiding frequency bias and independence assumptions of prior work and delivering superior accuracy and efficiency.
